Below are two dipoles for comparison.
Take a good look at the Gain figure at
higher angles for the above low dipoles. Great for close-in
communications, but the gain is still fairly high even at 45 degrees.

Below are two verticals for comparison. Take a good look at the
gain figures, and compare them to the low STL and the dipole above. The results might surprise you.

At first glance, it might look like we've improved things
at low angles. However, notice that even though we have greatly
decreased the high-angle radiation, the low angle gain is much lower
due to
earth losses. Verticals come into their own near saltwater, but not
over lossy ground.
